A B mssmr a COMPANY, OF. CHICAGO, ILLINOIS, A CORPORATION OF. ILLINOIS f fees CLEANING rrABaTi s] 7 Application filed March a;

This invention relates to improvements in gas cleaningapparatus of the in which there is employed rotating elementsoperating to beat up the water contained in the gas into a finely divided mist and then cause the mist tocohere into drops sufiic'iently large to permit their removal from the gas stream.

This cohesion and remo valis at present accomplished by means of a water'eliminaitor through which the gas passes after leaving the disintegrator. i The disintegrator-in connection withwhich this invention is particularly concerned em 'bodies a plurality of rows of rotating disintionary rows of bars;

It is one ofthe objects ofthe'present invention to change the 'form and construction of the outer rows of rotating bars to cause a cohes'ionofthe particles ofmist as they leave them. In the rapic'lcircular motion of this outer row of disintegrating bars, the mist strikes against the forward face of the bars this action.

In order to increase the tendency to enlargement of globules, there ;;is provided means projecting laterally-from the face of the bars of the outer row alonguthe outer edge thereof and in suc'lrprojections 'thereis formed a-series of gradually reduced passageways opening through the periphera3-l edge of the projections, in such a way that the globules of water Will'be diverted from a straight path tendencvto enlargement of-water globules and merged together in the gradually narrowing spaces to pass therethrough and to be thrown outwardly .at the outer edges of the f [,bars. The result of such a construction is that there is atendency to decrease thenumher and increase' the size of drops of water passing ofttheedgesofithe bars.

To the attainment of-theseendsandtheaccomplishment of other new and .useful ob- ;jects as will-appear, the invention consists in the features of novelty the construction, combination and arrangement of theiseveral parts hereinafter. :more fully described .;and

Referringmore particularly to the drawings the numeral 10 designates generally a casing inywhich the disintegrator is mounted, and the casing is provided withan inlet--11 throughwhich the gas to be treated enters,

and anoutlet 12 for the dry gas.

Arranged within-the casinglO is a disintegratorwhichconsists of arotor embodying a shaft 13 suitably mounted, and encompassing the sh-aftis a-housing 14, of a diameter-considerabl-y greaterthan-the diameter ofthe shaft,

' and arranged in-the wall of the housing l4= are tubularmemhers 15 through which the gas which enters the housing is discharged,

Secured to the shaft 13 in anydesired or suitable manner suchas by means of hub members 16 -and fastening devices 17, located within the housing 14, is 'adisc 1'8 whichgis'of a diameter considerably greater than the external diameter of the housingl i and-passes through the housing wall, the ;honsing"14, hub members 16rotating with the shaft. Supported in any desired or suitable man- 1 1 '66, Figv 55 of the bar. A

ner preferably by the wall of the casing 10 is a screen or reticulated member 19 which extends across and is spaced from theends of the tubular members 15. This screen 19 may be formed of any suitable material having openings 20 therethrough to permit thev gas which passes outof the tubular members 15 to pass therethrough.

Supported by the disc 18 and beyond the screen 19 are a-plurality of bars 21 spaced from each other and arranged in series parallel with each other. The outer ends of these bars are supported in any suitable manner such as by means of rings 22 so that when the disc 18 is rotated the bars 21 fw'illbe also rotated. These bars 21, as shown more clearly in Figure 3, are of a substan ially T shape in cross section, the web 23 thereof being dis posed in the rear of the bar while the face 2a is disposed at the front of the bar, with the result that during the operation of the device and when gas passes through the screen 19 into the path of movement of the bars or members 23, the outer face 24 of the bars will contact with the gas, with the result that moisture 35. tail or trailing portion 2301' the bar is short in comparison to the radial length of the bar andstiffensor reinforces the bar against the pressure of water and gas through which it forces its way. The radial length of the bar '(that is radial withreference to the orbit of its path of movement) isnecessary to withstand the stress of the centrifugal changes set up by the rapid rotation.

The advancing orvstriking surface of the bar is slightlydished or concaved, in order to reduce weight, and at the same time this surface prevents gasand water from glancing off-the bar too rapidly, thereby increasing the impinging effect of the bar on the gas- The bar may be formed in any suitable manner as an integral structure by castlng or molding, or by milling out of a solid bar, to a flat bar carrying a laterally projecting tail piece of substantially shorter length than the width Alternately arranged with the bars 21 are series of stationary bars 25, the latter being preferably supported by the wall of the easmg 1O, as shown in Figure 2, while the inner V ends of these stat onary bars 25 which are dis 7 posed on opposite-sides of the disc 18 are con- 0 nected together by means of rings 26.

I It will therefore be manifest that when the gas is contacted with thebars 21 the larger particlesor drops of water will adhere to the faces of the bars and will be thrown out or away from such faces during the rotation of the device. The contact of these bars will also cause particles of moisture in the mist to be formed into larger drops and in order .to cause a greater coherence of these smaller slots 29 opening through the top of the projection, thereby forming a narrow outlet for the gas which entersthe passages or recesses 28, with the result that when the outer bars 7 21 are rotated the globules of water in the gas willihe diverted from a straight path and merged together in the gradually narrowing space terminating in the slot 29 through the top of the projection 27. The tendency of this operation being to decrease thenumber and increase the size of the drops of water passing 05 the outer edge of the bars.

It will therefore be seen that in the rapid circular motion of the outer row of bars 21' the mist will strike against the forward surface 2 1of the bars and will tend to project or throw the same outwardly beyond the periphery, but in the course of such movement the gas comes into contact with the projection 27 and will enter the gradually reduced spaces 28 to pass through the slots 29 and thrown outwardly off of the edge of the bars, resulting in merging together of the drops of water in the mist, with the further result that the cohered drops will separate or. fall out of the gas.

WVhile the preferred forms of the invention have been herein shown and described, it is to be understood that Various changes may be madein the details of construction and in the combination and arrangement of the several parts, within the scope of the claims, without departing from the spirit of this invention.
